Title: Refractor-reflector radiation concentrator - uses components in co-operation to focus solar radiation from linear echelon and obtain high heat flux
Inventor: ANDERSON RAYMOND H
IPC: F24S23/70
Filed: 1978-09-12
Abstract: The small-area focus solar concentrator comprises a linear echelon refractor and a linear echelon reflector. The increments of the refractor are crossed at approximately 90 deg. to the increments of the reflector. The refractor and reflector cooperate to focus solar radiation incident on the front surface of the refractor to a small area focus in front of the refractor. The refractor-reflector structure permits relatively low cost, high power concentrators using refractor-reflector matrices. Also, the structure can be used to focus normal or non-normal incident radiation outside the path of the radiation to reduce or eliminate blockage of the radiation by an absorber located at the focus.

Title: Target distance measurement using EM radiation - derives signals from transmitted and reflected pulse trains, and compares them (OE 15.4.79)
Inventor: RIEGL JOHANNES DIPL ING DR
IPC: G01S17/14
Filed: 1978-12-05
Abstract: The radiation is in the range from ultraviolet to infrared. A transmitter and a receiver with electro-optical transducers are used. The measurements are based on pulse propagation time with periodically transmitted pulses from a generator (3) controlled by a quartz oscillator (1). A periodic signal is derived from the receiver (5) pulse train delayed w.r.t. the transmitted signal, which is at least in one part monotonic decreasing or increasing, such as a sinusoidal signal. A similar signal is derived from the transmitted (4) pulse train, and both signals are compared. Phase shift is caused by the pulse propagation time, i.e. the distance to the object, and is used for the distance determination.

Title: Centrifuge spin head - accepts baskets in angled carrier pins for greater mechanical strength
Inventor: BOTTLING MANFRED
IPC: B04B5/04
Filed: 1979-01-03
Abstract: The spin heads at the ends of the spider arms of a centrifuge accept the baskets contg. the articles to be centrifuged in short carrier pins which are inserted in intersecting bores. These pins are not designed as straight stepped stubshafts but are angled outside the bores. The result is that the bores can have an angle of intersection which is =90 degrees for the same width of opening between the spin heads. The heads are mechanically stronger therefore and a higher speed is acceptable for the centrifuge.

Patent DE-2926634-A1 (DE)
Inventor: TSCHANNEN GOTTFRIED
IPC: H03B21/00
Filed: 1979-07-02
Abstract: When testing radar Doppler systems, it is necessary to simulate a frequency shift which occurs between a transmitted signal and a signal received from a moving target. The circuit arrangement is used for generating a test signal, the frequency of which corresponds to the sum or the difference of the frequencies of two predetermined signals. For this purpose, the phase of the first signal is continuously shifted by a total of 2 pi  during the period of the second signal by means of two phase shifters (P1, P2). This leads to the frequency of the first signal being shifted by the amount of the frequency of the second signal since, in the case of a frequency addition, the phase of the first signal is shifted from - pi /2 to + pi /2 by the first phase shifter (P1) during the first halves of the periods of the second signal and from  pi /2 to 3 pi /2 by the second phase shifter (P2) during the second halves of the periods of the second signal. In the case of frequency subtraction, the phase of the first signal is shifted from + pi /2 to - pi /2 by the first phase shifter (P1) during the first halves of the periods of the second signal and from 3 pi /2 to  pi /2 by the second phase shifter (P2) during the second halves of the periods of the second signal. <IMAGE>

Title: Warp yarn tension monitor - uses fixed deflection forces to measure yarn response to determine tension
Inventor: BRASSARD HANS-JOACHIM A DIPL C
IPC: D02H13/26
Filed: 1979-08-03
Abstract: The yarns under test are all of the same type for the same purpose, such as for warping, and are deflected from their plane of travel to the warping beam, into a path of defined length for measurement, and then returned to their original path. In the measurement path phase, the yarns are further deflected in a given order with a given force. The amount of deflection allowed by each yarn is measured, and/or registered and/or used as a constant for control units to handle the yarns.. The process allows the drawing forces on the yarns to be monitored, so that the individual yarns can be adjusted before being worked into a fabric.
